For the purpose of this review the Nikon AF Nikkor 50mm F/1.8D was used with Nikon D80 DSLR.
The images which illustrate this review were developed in Capture One WITHOUT correction of distortion, vignetting and lateral chromatic aberrations, WITHOUT sharpening and increasing of overall contrast, brightness, saturation and WITHOUT changing of any other settings, except for vividness.
The resolution at the center of the frame is very good at F/1.8-2 and excellent from F/2.8 and up to F/8. The edges of APS-C fra,e are good at F/1.8-2.8, very good at F/4 and excellent at F/5.6-8. It’s a typical result for a fast prime lens with focal length of 50-55 mm.
The lens does not show any noticeable distortion — a lens of 50-55 mm class rarely suffers from strong distortion. Being a full-frame lens, it forms the image circle which cannot be fully used by the APS-C sensor (the sensor cuts the edges of the image where exactly distortion shows itself).
Longitudinal chromatic aberrations are noticeable at F/1.8 but disappear with further closing of the aperture. Lateral chromatic aberrations can be described as moderate at F/1.8-2.8 but you won’t notice them at images with blurred background. The aberrations become unnoticeable with significant closing of the aperture (F/5.6 or more).
Vignetting is weak at F/1.8 and won’t be a problem at all with further closing of the aperture.
